Last November the New York Times described the un-ethical business practices of the online eyewear vendor DecorMyEyes. The website was very well ranked in many popular Google search results related to designer glasses. Thanks to numerous consumer complaints on opinion-sharing websites, DecorMyEyes received many backlinks from popular websites and benefited from an increasing PageRank.
To prevent scammers from gaining any visibility thanks to consumer complaints, Google decided to penalize websites receiving too much negative content. Of course integrating automatic sentimenting to the algorithm had its downfall; all controversial or political content was bound to be penalized. To counter this effect, Google decided to blacklist a limited number of e-commerce websites that receive an unusual amount of flak from consumers.
